Creating a table by extracting rows from a table based off their values in relation to another table of a different size.

I have two tables of different size, for example, I have a 16x4 table with headers a,b,c and d and I have another 6x2 table with headers c and d. I have constructed both tables in matlab

a = [11;33;55;77;99;23;45;67;89;87;65;43;10;1;3;5];
b = [22;44;66;88;12;34;56;78;98;76;54;32;21;2;4;6];
c = [2;2;2;2;4;4;4;4;6;6;6;6;8;8;8;8];
d = [2;4;6;8;2;4;6;8;2;4;6;8;2;4;6;8];

T1 = table(a,b,c,d)

cc = [1.2;1.6;5.5;6.7;5.9;2.3];
dd = [2.5;4.6;3.5;3.2;1.5;1.9];

T2 = table(cc,dd)

T3 = T1(abs(T1.c-T2.cc)<=1 & abs(T1.d-T2.dd)<=1)

I wish to construct another table by filtering out rows based on values of abs(c - cc) <= 1 and abs(d - dd)<= 1 as the conditions and construct a new table using the extracted rows. looking like this in due to the order of the previous table t2:

.

But I couldn't do it as the number of variables are different. Any help will be appreciated!

a = [11;33;55;77;99;23;45;67;89;87;65;43;10;1;3;5];
b = [22;44;66;88;12;34;56;78;98;76;54;32;21;2;4;6];
c = [2;2;2;2;4;4;4;4;6;6;6;6;8;8;8;8];
d = [2;4;6;8;2;4;6;8;2;4;6;8;2;4;6;8];
T1 = table(a,b,c,d)

T1 = 16×4 table

ixc = any((T1.c-reshape(T2.cc,1,1,[]))<=1,3);

I am sorry, but your output is different from my intended output. is it due to the lack of the absolute sign? I'd appreciate it if you could explain the code!
